Rad Vocab

In your EarthResources notebook, you should add these lines to the Radioactivity page:

• “Irradiated” vs. “Radioactive”
• It happened already vs. It will happen again and again
• Blast of Energy vs. Potential Energy
• Write out an example that shows the difference between the two words! (Hint: radioactive teacher, Homer Simpson, PSU Salt…)
